Product Overview

What are ASTM A193 Grade B16 Threaded Rods?

ASTM A193 Grade B16 threaded rods are high-strength alloy steel fasteners manufactured from chromium-molybdenum-vanadium steel, specifically designed for high-temperature and high-pressure bolting applications. These rods are produced from material conforming to ASTM A193 B16, which requires a minimum tensile strength of 860 MPa (125 ksi) and are typically supplied in the quenched and tempered condition.

ASTM A193 B16 threaded rods are widely specified for use in petrochemical, power generation, and refinery applications, especially where elevated temperatures up to 593°C (1100°F) are encountered. Their superior creep resistance and mechanical stability make them the preferred choice for critical flange connections, pressure vessels, and heat exchanger assemblies.

Material Chemistry

ASTM A193 Grade B16 Chemical Composition

ASTM A193 Grade B16 Threaded Rods are manufactured from chromium-molybdenum alloy steel with Cr (0.8–1.1%), Mo (0.15–0.65%), and vanadium additions in B16 grades, controlled per ASTM and ASME SA-193. Cr-Mo additions raise hardenability and creep rupture strength for pressure vessel service; vanadium in B16 extends the allowable service temperature to 538°C.

Why ASTM A193 Grade B16 Alloy Composition Matters for Threaded Rods

Cr-Mo-V Alloy — High-Temperature Strength
The combination of chromium, molybdenum, and vanadium in ASTM A193 B16 provides exceptional strength retention and creep resistance at elevated temperatures, making these rods ideal for steam, hydrocarbon, and power plant bolting.
Controlled Carbon Content
A tightly controlled carbon range ensures a balance between tensile strength and ductility, reducing the risk of brittle fracture in high-stress environments.
Low Phosphorus & Sulfur
Strict limits on phosphorus and sulfur minimize the risk of embrittlement and improve weldability, ensuring reliable performance in critical service.

ASTM A193 Grade B16 threaded rods are available in ISO metric (DIN 976-1), UNC/UNF (ASME B1.1), and custom thread forms such as BSW or BSF on request. Inch sizes are supplied per ASME B18.31.3. Special threads for OEM equipment can be produced with a 2-3 week lead time.
Use molybdenum-based anti-seize compound (such as Molykote 1000 or Loctite LB 8012) for assembly. Apply to threads and nut faces to prevent galling and facilitate disassembly after high-temperature service. Avoid copper-based anti-seize in applications above 400°C to prevent galvanic corrosion and softening.
Yes – ASTM A193 B16 rods are specifically engineered for high-temperature bolting up to 593°C (1100°F). Their Cr-Mo-V alloy composition ensures excellent creep resistance and mechanical stability in steam, hydrocarbon, and power generation environments.
